Abstract
Graphene Oxide Nanoplatelets (GONPs) have been produced from Pristine Graphene Oxide (PGO) using ball-milling and characterized using FTIR, XRD, SEM/EDS and TEM. Effects of 0.1wt% and 0.125wt% of GONPs and PGO on compressive strength and direct-current (DC) electrical resistivities of cement nanocomposites at 7, 14, 28 and 90days are studied. Microstructural, thermal and crystalline behavior of 90-days cured nanocomposites have been investigated using SEM, TGA and XRD respectively. Enhancement of 33% in strength is obtained with 0.125% GONPs with an electrical resistivity of 2.32×106ohm.cm. Hexagonal platelets of hydration products having uniform orientation were produced after 90days.
